@Gayle32 Could be because the average stars on that listing is 4.12.... that is pretty low, by Airbnb standards. Basically, they consider every review that's not 5 stars to be a fail. So even if the written review looks fine, if the guest gives you less than 5 stars, it's a black mark against you.
I'm assuming this is just a temporary block? Your other listings do appear to be bookable. I would also follow up on Twitter @airbnbhelp.
One thing that stood out for me on your recent reviews is that you respond to pretty much every review, except for the one that mentions cleanliness (which has also been mentioned in prior reviews). I definitely would have said something in response to that. Also, don't respond publically to private feedback. If your potential guest can't see what the past guest said, there's no reason to bring it up .
